Well so far our attempts to "keep them locked up" has made life a LOT worse for millions of people.
We went to Iraq to "keep them locked up". The people of Iraq are MUCH worse off than before we intervened.
We supported efforts in Libya to "keep them locked up". The people of Libya are MUCH worse off then before we intervened.
We went to Afghanistan to "keep them locked up". The people of Afghanistan are MUCH worse off due to our intervention.
We also have made life worse for the people of Yemen and Honduras.
All of this just to keep these countries "not internationally significant"???
The money we spent to destroy so many countries could have bought an awful lot of much needed infrastructure improvements in the United States.
